Patent ES-362055-A1 (ES)
Title: Potassium silicate coated silicon steel article
IPC: C21D1/70
Filed: 1969-01-02
Abstract: Coated silicon steel stock is obtained by hot reducing the silicon steel, removing the scale, cold-rolling to final gauge, subjecting the stock to a final anneal, providing the surfaces of the stock with a film of mill glass, or a layer of phosphate or a coating of both and subsequently applying an aqueous solution consisting essentially of potassium silicate and heating the coated stock to a temperature above 1,000 F to form a potassium silicate glass coating on the stock. The potassium silicate may have silica to potassium oxide ratio of 2:1 to 2.5:1 and heating may be at 1,000-1,650 F. The heating step may comprise a strip anneal and may be conducted in an atmosphere of air, nitrogen or hydrogen or mixtures of these, or partially combusted natural gas. A flash pickling may be effected before application of the potassium silicate solution.

Title: Process for the isomerization of aliphatic hydrocarbons
IPC: B01J27/06
Filed: 1969-03-27
Abstract: Hexafluoroantimonic acid is prepared by reacting SbCl 5 with excess liquid HF, optionally while stripping the mixture with inert gas, e.g. N 2 or gaseous HF. Preferably the liquid HF reactant is boiling and thus provides the stripping gas in situ, the reaction being continued until evolution of HC1 vapour ceases. Excess liquid HF may then be boiled off to give product acid of desired concentration. In specific preparations the final product is SbF 5 .2HF, i.e. hexafluoroantimonic acid diluted with an equimolar amount of HF.
Patent ES-377040-A1 (ES)
Title: A method of making a metal impregnated grinding tool
IPC: B24D18/00
Filed: 1970-02-28
Abstract: Metal bonded abrasive tools are manufactured in which the abrasive grits are uniformly spaced and distributed throughout the tool, by encapsulating one or several abrasive grits in a porous layer of powdered metallic material and preferably sintering the layer, thereby forming individual abrasive grit containing particles which are then placed in a mold and the spaces between the particles filled with a conventional metallic bonding agent. Heat, and in some instances heat and pressure, is applied which permanently binds the mixture together in the desired form. The process is particularly well suited for the fabrication of metal bonded diamond wheels where the metal-bond to diamond-grit volume ratio is relatively high.

Patent ES-466874-A1 (ES)
Title: Apparatus for preventing sparks in the ignition system of an engine while the engine is at rest
IPC: F02P9/00
Filed: 1978-02-10
Abstract: The voltage in the secondary of an ignition coil is prevented from reaching an amplitude at which a spark might be created by a Zener diode connected in parallel with the series transistor acting as a switch which interrupts the current through the primary winding of the coil. Upon breakdown of the Zener diode, the series transistor is switched to the conductive state briefly, thereby preventing further voltage build-up in the secondary. When the engine is in operation, a transistor which forms part of a voltage divider is switched to the conductive state, connecting the voltage divider between the secondary winding and the Zener diode. The voltage divider is so dimensioned that the Zener diode will respond to a voltage slightly less than the breakdown voltage of the emitter-collector circuit of the series transistor, but higher than the voltage required for creating a spark.
